stoney, a lack of comprehension of BA's fare structure was not the problem.

The complaint is that some people went to a lot of trouble to create a sticky that has a specific section about "Tiers and Tier Points", which contains the exact answer to your question. It's indexed as such in the contents list, and it's very easy to find - and it is way before the Fare Classes section which you quoted.

So I think the sarcasm is a little out of order.
